There is such a temperature. We are not getting to it in half a century at current emission rates, even with zero curtailment. If you have a source that shows the opposite, I’d be happy to read it.
Of course not in half a century, but it's not like the earth just stops getting hotter after 2100 rolls around.
What about 2200? Humanity at 2300? It's the same planet with the same feedback loops after all.

You literally said “the existential threat happens in 100 years.”
And to your questions, we don’t know. I’d love to see the data. I’m still sceptical we hit “existential” levels for human survival. That wouldn’t even happen if we went back to dinosaur levels of CO2.
